Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Furthermore, it should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the invention, are given by way of illustration and explanation only, and are not intended to limit the scope of the invention. In the present application, the terms "inner", "outer", "front", "rear", "left", "right" and "vertical" are used with reference to the accompanying drawings without being described to the contrary.

The embodiment of the application provides a control box, and the control box is used for forming a lamp with a light source.

The control box includes a housing 100. Referring to fig. 1, fig. 2 and fig. 3, the structure of the casing 100 in different viewing angles is schematically illustrated, and it can be seen that in the present embodiment, the casing 100 is composed of a box body 100a with one side in an open shape and a box cover 100b covering the open end of the box body 100 a.

Referring to fig. 4, it can be seen that the housing 100 encloses an interior 110 for receiving the electrical devices 300 in the control box, the interior 110 having the heat dissipation structure and the plurality of electrical devices 300 disposed therein. The heat dissipation structure includes a plurality of heat dissipation covers 210 disposed in the inner cavity 110 at intervals. The plurality of heat dissipation covers 210 are spaced from each other, that is, the heat dissipation covers 210 are separated from each other in the space 113, and are formed with a space and do not contact each other, so that a space 113 with a proper size is formed between the inner wall of the inner cavity 110 and the heat dissipation cover 210 and between two adjacent heat dissipation covers 210. A plurality of electric devices 300 are respectively disposed in a space 113, separated by the heat dissipation cover 210.

The heat dissipation cover 210 can generate a temperature field with a lower temperature under the action of the airflow. In detail, in the present embodiment, as shown in fig. 3 and 4, the opposite ends of the casing 100 are respectively formed with an air inlet 111 and an air outlet 112 which are communicated with the inner cavity 110, the heat dissipation cover 210 is formed with a flow channel 220 whose two end ports are respectively communicated with the air inlet 111 and the air outlet 112, and the heat dissipation structure includes a plurality of fins 230 respectively disposed in the flow channels 220. Here, the fins 230 refer to heat dissipation fins, and a plurality of fins 230 are arranged in the flow channel 220 side by side at intervals and connected to the inner wall of the flow channel 220. When the airflow flowing from the air inlet 111 to the air outlet 112 passes through the flow channel 220, the airflow can generate heat convection with the heat dissipation cover 210 and the fins 230, so that the temperatures of the heat dissipation cover 210 and the fins 230 are reduced.

It should be noted that the structural form of each heat dissipation cover 210 and the structural form of the fins 230 in each flow channel 220 can be adjusted according to the needs of the practitioner. It is understood that the structural form of each heat dissipation cover 210, the number of teeth, the tooth height, the tooth thickness, and the tooth space of the fins 230 may be the same or different. In addition, the heat dissipation cover 210 is not limited to the shape shown in the present embodiment, which is open at two ends and closed at the periphery. The fins 230 are not limited to the straight tooth pattern shown in the embodiment, and the fins 230 may be configured to extend linearly or extend in a curved manner, as long as the fins 230 can perform heat convection with the airflow in the flow channel 220 during the airflow passing through the flow channel 220.

When the control box is in operation, the air flow enters the inner cavity 110 from the air inlet 111 of the housing 100 and is finally discharged from the air outlet 112. In the process, the airflow enters the flow channels 220 in the heat dissipation cover 210, passes through the fins 230, and generates convective heat exchange with the heat dissipation cover 210 and the fins 230, so that the temperature of the heat dissipation cover 210 and the fins 230 is reduced. When the control box is in operation, the heat dissipation cover 210 located between the two electric devices 300 forms a temperature field with a lower temperature between the two electric devices 300, and blocks and isolates the two adjacent electric devices 300 respectively located in the two adjacent spaces 113. Therefore, the heat emitted from two adjacent electric devices 300 may not overlap each other, thereby effectively improving the operational reliability of the electric devices 300 and preventing the heat of the control box from being concentrated.

It should be noted that the electric device 300 refers to an electronic component having a structure of a resistor, a capacitor, an inductor, a controller, and the like. In this embodiment, the plurality of electric devices 300 includes a plurality of circuit boards and adapter modules, the circuit boards are electrically connected to the light sources to allow the light sources to perform corresponding functions according to their circuit structures, and the adapter modules are electrically connected to the power sources and the light sources to realize power supply voltage conversion. The practitioner may select the specific type of the electrical device 300 according to the needs without affecting the purpose of implementation. For example, in another embodiment, the plurality of electric devices 300 further includes a power module, a controller, and the like.

It should be further noted that, in this embodiment, as shown in fig. 4, the number of the components of the heat dissipation cover 210 is specifically two, the two heat dissipation covers 210 are sequentially arranged along the vertical direction, and a distance is formed between the two heat dissipation covers and the inner wall of the inner cavity 110 in the vertical direction, so as to divide the inner cavity 110 into three spaces 113. Correspondingly, in the present embodiment, the number of the specific components of the electric device 300 is three, and the three components are respectively disposed in a corresponding one of the spaces 113. It is understood that the arrangement of the heat dissipation covers 210 is not limited thereto. For example, in another embodiment, the number of components of the heat dissipation cover 210 is three, and the components are also arranged in sequence in the vertical direction. In the vertical direction, the heat-radiating cover 210 on one side is in close contact with the inner wall of the inner cavity 110, and the heat-radiating cover 210 on the other side is spaced from the inner wall of the inner cavity 110, so that the three heat-radiating covers 210 divide the inner cavity 110 into three spaces 113.

The space 113 can be divided into two types, namely, a first space 113a defined by the heat dissipation cover 210 and the inner wall of the inner cavity, and a second space 113b defined by two adjacent heat dissipation covers 210. In this embodiment, the power of the adapter module is significantly higher than that of the circuit board, the heat emitted by the adapter module during operation is significantly higher than that emitted by the circuit board, and the requirement of the adapter module for heat dissipation is higher.

To the adapter module isopower higher, the great first electrical device 310 of heat that gives off when moving, the implementer can set up it between inner chamber 110 inner wall and heat exchanger 210 to expect that the heat that first electrical device 310 gave off can pass through heat exchanger 210, inner chamber 110 inner wall simultaneously and transmit to the external world, thereby satisfy its first electrical device 310 thermal demand. For example, in the present embodiment, as shown in fig. 5, the at least three spaces 113 include a first space 113a formed between the inner wall of the cavity 110 and the heat dissipation cover 210, and the first electric device 310 is located in the first space 113 a.

For the circuit board, which is a kind of second electric device 320 with low power and moderate heat dissipation, the second electric device 320 can be disposed in the second space 113b defined by two adjacent heat dissipation covers 210, so as to avoid the waste of performance caused by surplus heat dissipation capability of the heat dissipation covers 210. Of course, the second electric device 320 may be disposed in another first space 113a as long as there is an excess first space 113a where the first electric device 310 is not disposed, without affecting the purpose of implementation, and this is not particularly limited in the present application.

It will be appreciated that the first electrical device 310 and the second electrical device 320 are differentiated by power, with the first electrical device 310 being more powerful than the second electrical device 320. In addition, the practitioner may set a preset power value as a division standard of the first electric device 310 and the second electric device 320. For example, when the power of the electric device 300 is more than 20w to 50w, for example, 40w, the power thereof is larger, and it is necessary to independently dissipate heat as the first electric device 310. When the power of the electric device 300 is less than 20w to 50w, for example, 40w, the power thereof is moderate, and it can be used as the second electric device 320 to dissipate heat. Furthermore, the above description of the adapter module and the circuit board is merely illustrative of the specific type of electrical device 300 and it should not be understood that either the first electrical device 310 must be the adapter module or the second electrical device 320 must be the circuit board.

Further, in this embodiment, the electrical device 300 is thermally coupled to at least one heat sink 210 that defines the space 113 in which it is located. The heat exchange between the electrical device 300 and the corresponding heat dissipation cap 210 may be either thermal conduction or thermal convection. In the present embodiment, the circuit board and the adapter module are both in contact with the heat dissipation cover 210 of the corresponding heat dissipation cover 210, so as to establish a heat conduction relationship with the corresponding heat dissipation cover 210, and the heat dissipated by the electric device 300 during operation is conducted to the corresponding heat dissipation cover 210 through the portion of the heat dissipation cover that is in direct contact with the heat dissipation cover 210. In addition, in order to secure the heat dissipation effect, in the present embodiment, as shown in fig. 4, the arrangement direction of the plurality of heat dissipation covers 210 is the first direction, and the ratio of the area of the projection of the electric device 300 in the first direction to the area of the projection of the heat dissipation cover 210 in the first direction is greater than 1.

Further, in order to better enable the heat emitted from the first electric device 310 to be simultaneously transferred to the heat dissipation cover 210 and the external environment. In the present embodiment, as shown in fig. 5, the inner wall of the inner cavity 110 includes a heat conducting wall 114 opposite to the first heat dissipation cover 211 to define a first space 113a, and the first electrical device 310 is in contact with the first heat dissipation cover 211 and the heat conducting wall 114 respectively. Because the first electric device 310 is in contact with the first heat dissipation cover 211 and the heat conduction wall 114 at the same time, a part of heat generated by the operation of the first electric device 310 is transmitted to the first heat dissipation cover 211 and absorbed by the first heat dissipation cover 211, and a part of heat is transmitted to the heat conduction wall 114 and absorbed by the external environment, so that the heat dissipation efficiency of the first electric device 310 in the control box is effectively improved.

It should be noted that the heat conducting wall 114 forms a part of the housing 100, and a surface of the outer contour of the housing 100, which faces away from the heat conducting wall 114, may be provided with a heat dissipating strip, a heat dissipating groove, or the like, so as to more quickly dissipate heat to the external environment. In addition, in this embodiment, the adapter module specifically includes two adapter units, and the two adapter units are arranged side by side and are both connected to the first heat dissipation cover 211. So set up, can make the heat distribution of adapter module more even, reduce thermal concentration in the control box.

Meanwhile, in the present embodiment, the number of the above-described second electric devices 320 is plural. As described hereinbefore, the second electric device 320 is low in power and generates moderate heat during operation. Therefore, the margin is provided for avoiding the heat dissipation capability of the heat dissipation structure. In the present embodiment, as shown in fig. 5, the plurality of heat dissipation covers 210 includes a second heat dissipation cover 212 adjacent to the first heat dissipation cover 211, the number of the second electrical devices 320 is plural, and two second electrical devices 320 of the plurality of second electrical devices 320 are respectively disposed in the spaces 113 on both sides of the second heat dissipation cover 212 and respectively contact with the second heat dissipation cover 212, so that the second electrical devices 320 on both sides are both in heat conduction relationship with the first heat dissipation cover 211, and the first heat dissipation cover 211 simultaneously dissipates heat of the second electrical devices 320 on both sides.

It is worth mentioning that the second electric devices 320 on both sides may be in direct contact with the second heat dissipation covers 212, respectively. If the implementer desires to obtain a more desirable heat dissipation effect, a heat dissipation silicone may be disposed between the second electric device 320 and the second heat dissipation cover 212, so that the second electric device 320 and the second heat dissipation cover 212 are indirectly contacted through the heat dissipation silicone, thereby obtaining a more desirable heat conduction effect.

In addition, the first electrical device 310 is more powerful and releases more heat during operation. If the second electric device 320 is simultaneously connected to the first heat dissipation cover 211, the heat dissipation effect of the first electric device 310 may be affected.

Therefore, in the present embodiment, the second electric device 320, which is located between the first heat dissipation cover 211 and the second heat dissipation cover 212, is disposed spaced apart from the first heat dissipation cover 211. The first heat dissipation cover 211 and the second electric device 320 are spaced apart from each other, that is, separated from each other in the space 113, formed with a space, and do not contact each other. At this moment, the first heat dissipation cover 211 does not form an effective heat conduction relationship with the second circuit component, so the first heat dissipation cover 211 mainly dissipates heat to the adapter module, the heat dissipation effect of the control box on the first electric device 310 is ensured, the isolation between the first electric device 310 and the second electric device 320 is improved, and the mutual influence of the first electric device 310 and the second electric device 320 on the respective heat dissipation effect is avoided.

As described above, the implementer can correspondingly adjust the structural parameters of the fins 230 in each of the channels 220 according to his/her own requirements, so as to obtain a more ideal heat dissipation effect.

The first electrical device 310 with a higher heat dissipation requirement is addressed. Referring to fig. 6 and 7, the number of the first fins 231 in the flow channel 220 of the first heat dissipation cover 211 may be 17 to 23, for example, 20 shown in this embodiment. The thickness of each first fin 231 in the arrangement direction thereof may be 1.5 to 2.5mm, such as 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, and 2.5mm, or a value therebetween. The distance between two adjacent first fins 231 may be 6.5 to 7.5mm, such as 6.5mm, 6.6mm, 6.7mm, 6.8mm, 6.9mm, 7.0mm, 7.1mm, 7.2mm, 7.3mm, 7.4mm, and 7.5mm, or a value between any two of them. The first heat sink cover 211 with the first fins 231 having such parameters can satisfy the heat dissipation requirement of the first electric device 310.

The second electric device 320 for which the heat dissipation requirement is moderate; referring to fig. 6 and 7, the number of the second fins 232 in the second heat dissipation cover 212 may be 12 to 18, for example, 15 shown in this embodiment. The thickness of each second fin 232 in the arrangement direction thereof may be 1.5 to 2.5mm, such as 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, and 2.5mm, or a value therebetween. The distance between two adjacent second fins 232 may be 9.5 to 10.5mm, such as 9.5mm, 9.6mm, 9.7mm, 9.8mm, 9.9mm, 10.0mm, 10.1mm, 10.2mm, 10.3mm, 10.4mm, and 10.5mm, or a value between any two of them. The second heat sink cover 212 is configured with the second fins 232 of such parameters to meet the heat dissipation requirements of the second electrical device 320.

The structure of the control box has been described initially. The application scenes of the lamp are variable, and the warm and humid environment with harsh requirements on the heat dissipation performance and the waterproof performance of the control box is not lacked, so that the improvement of the waterproof performance of the control box has important significance.

The structure of the control box will be further described in conjunction with the application scenario of the control box.

The airflow entering from the intake vent 111 may contain some liquid under environmental influences, which may cause damage to the electrical device 300. In the present embodiment, since the first heat dissipation cover 211 and the second heat dissipation cover 212 are both in a shape with two open ends and a closed periphery, as shown in fig. 6 and 7, the first heat dissipation cover 211 has a first closing wall 213, the second heat dissipation cover 212 has a second closing wall 214, and the first closing wall 213 and the second closing wall 214 are disposed opposite to each other. The closed wall is a structural wall having a solid shape and capable of blocking liquid.

Wherein liquid may penetrate from between the first and second closing walls 213, 214 to the vicinity of the second electric device 320. Therefore, referring to fig. 6 and 7 again, the heat dissipation structure further includes a third enclosing wall 215, the third enclosing wall 215 is connected to the first enclosing wall 213 and the second enclosing wall 214 respectively, and the first enclosing wall 213, the second enclosing wall 214 and the third enclosing wall 215 enclose a space 113 for accommodating the second electric device 320, so as to improve the sealing performance of the space 113 where the second electric device 320 is located.

It should be noted here that, in the present embodiment, the number of the third closing walls 215 is two, and the third closing walls are respectively disposed on two opposite sides of the second electric device 320 in the left-right direction. This is because the air inlet cover 400 and the air outlet cover 500 are respectively provided on both sides of the second electric device 320 in the front-rear direction, and the risk of liquid intrusion into the vicinity of the second electric device 320 in the front-rear direction is low. It is understood that the specific number of the third closing walls 215 is not limited thereto as long as there is a third closing wall 215 connected to the first closing wall 213 and the second closing wall 214, respectively, that can improve the sealing of the environment where the second electric device 320 is located. Of course, it is desirable that the first and second enclosing walls 213 and 214 and the third enclosing wall 215 enclose a space 113 in a closed shape to further improve the sealing of the environment in which the second electric device 320 is located.

Further, in the present embodiment, as shown in fig. 5, one end of the flow channel 220 in the heat dissipation cover 210 is communicated with the air inlet 111 through the air inlet cover 400, and the other end is communicated with the air outlet 112 through the air outlet cover 500, so that the air inlet 111, the air inlet cavity 410, the flow channel 220, the air outlet cavity 510, and the air outlet 112 are sequentially communicated to form a closed or substantially closed heat dissipation channel.

Meanwhile, in the present embodiment, the control box includes a fan 600, and the fan 600 is disposed in the inner cavity 110 and is abutted between the air inlet 111 and the air outlet 112, so as to drive the external air flow to flow from the air inlet 111 to the air outlet 112 of the housing 100. It is to be understood that the above description should not be construed as limiting the construction of the control box, i.e., it should not be construed that the control box must contain the fan 600. The air flow inside the control box may be driven by other components located outside the control box.

So that the flow channels 220 of each heat dissipation cover 210 can be introduced with a suitable amount of airflow. In the present embodiment, referring to fig. 5 and 8 together, the wind inlet cover 400 has two ends and defines a wind inlet cavity 410, a first port 420 is formed on one end of the wind inlet cover 400 facing the wind inlet 111, and as shown in fig. 9, a number of second ports 440 corresponding to the number of the heat dissipating cover 210 are formed on the other end of the wind inlet cover 400 facing the heat dissipating structure. The first port 420 is communicated with the air inlet 111, and the second ports 440 are communicated with the flow channels 220 in a one-to-one correspondence manner, so that the airflow entering the air inlet chamber 410 is divided into a plurality of airflows by the second ports 440 and respectively led to the flow channels 220, thereby enabling the flow channels 220 in the heat dissipation covers 210 to receive the airflows independently.

The airflow entering from the intake 111 may contain some liquid, subject to environmental influences.

Similar to the air inlet cover 400, the air flow and the liquid contained in the air flow are easy to leak at the connection part between the air outlet cover 500 and the heat dissipation cover 210. Therefore, in the present embodiment, as shown in fig. 5 and 10, the wind outlet housing 500 has two ends and defines a wind outlet cavity 510, a number of second bosses 520 corresponding to the number of the heat dissipating housing 210 are formed on one end of the wind outlet housing 500 facing the heat dissipating structure, a third port 530 is formed on the second bosses 520, and a third sealing structure is provided, as shown in fig. 11, a fourth port 540 is formed on one end of the wind outlet housing 500 facing the wind outlet 112; the heat dissipation cover 210 is provided with a fourth sealing structure, and the plurality of third sealing structures and the plurality of fourth sealing structures are matched in a one-to-one correspondence manner, so that the plurality of third ports 530 are in one-to-one correspondence sealing communication with the plurality of flow passages 220, and the fourth ports 540 are communicated with the air outlet 112.

The implementer may correspondingly select the specific form of the third sealing structure and the fourth sealing structure according to the actual situation and the self requirement, and the application is not particularly limited to this.

It is understood that the specific number of the first bosses 430 and the second bosses 520 may be adjusted by an implementer according to the actual number of the heat dissipation covers 210, so as to improve the sealing performance of the heat dissipation channel. The number of the first bosses 430 and the second bosses 520 is not limited to two illustrated in the present embodiment.

It should be noted that, in order to prevent the liquid leakage from the communication position between the air outlet housing 500 and the air outlet 112, in this embodiment, as shown in fig. 5, one end of the air outlet housing 500 facing the air outlet 112 is in sealing fit with the inner wall of the inner cavity 110, so that the fourth port 540 is in sealing communication with the air outlet 112.

Further, in the present embodiment, the wind outlet housing 500 is directly connected to the inner wall of the inner cavity 110. Meanwhile, the air outlet cover 500 is directly connected with the heat dissipation cover 210, the air inlet cover 400 and the heat dissipation cover 210. At this time, if the air inlet cover 400 and the inner wall of the inner cavity 110 are directly connected, the manufacturing accuracy of the components may be increased or the installation may be difficult. Therefore, in the present embodiment, as shown in fig. 5, a gap is formed between one end of the air inlet cover 400 and the inner wall of the inner cavity 110, so as to form a gap for facilitating the installation of the components.

Here, the airflow drawn by the fan 600 may flow out of the heat dissipation channel at the gap, thereby reducing the amount of the airflow in the heat dissipation channel and affecting the heat dissipation efficiency of the control box. In the present embodiment, the fan 600 is disposed on a side of the intake cover 400 facing the intake opening 111 and partially extends into the intake chamber 410. The air flow is strongly drawn near the fan 600, and the air flow tends to converge toward the fan 600 and the air inlet chamber 410, so that most of the air flow enters the air inlet chamber 410 from the air inlet 111 under the action of the fan 600, and does not flow out of the heat dissipation channel through the gap, thereby ensuring the heat dissipation effect of the control box. More specifically, in the present embodiment, as shown in fig. 1 and 5, the number of the components of the fan 600 is two, and the two components are arranged side by side between the inner wall of the inner cavity 110 and the air inlet cover 400.

It will be appreciated that an ideal heat sink channel should have a low aerodynamic resistance in order to accelerate the flow rate of the air flow in the control box and to increase the amount of air flow entering the control box. Therefore, in the present embodiment, as shown in fig. 5, the heat dissipation channel in the control box is configured to extend linearly, and the cross section of the inner wall of the heat dissipation channel perpendicular to the extending direction of the heat dissipation channel is rectangular, that is, the cross section of the inner wall of the air inlet cavity 410, the air channel 220 and the air outlet cavity 510 perpendicular to the extending direction of the heat dissipation channel is rectangular. The heat dissipation channel extends linearly, the path is shorter, and the section of the inner wall of the heat dissipation channel is rectangular, so that the pneumatic resistance of the whole heat dissipation channel is lower, the air flow can rapidly pass through the flow channels 220, more air flows can pass through the flow channels 220, and the heat dissipation effect of the control box is improved.
